you're somewhat limited with i think a max of 8 characters. so anything other than name/initials/ or very short saying, isn't going to work. won't be able to get anything like some of the tour guys are getting these days with a phrase on the club. whatever you get, make sure it's what you want, not what you think might be "cool" or trendy at the time. if you're making this investment, i'm guessing you don't plan to replace them next year.
